The system includes: a voltage source; a MOSFET SWITCH gate driver, in USB type-A connected state, that operatively couples MOSFET SWITCH with voltage source and VBUS supply of USB type-A port; charge pump; a current sense differential amplifier; and a control unit configured to: monitor VBUS current, and detect potential disconnected state of connected USB type-A port; and monitor VBUS voltage and compare VBUS voltage with predetermined voltage to sense external condition such that VBUS voltage drops because of load capacitance and load current. The control unit is further configured to, when the duty cycle has reached a minimum VBUS current, detect the USB type-A disconnection with a charge pump state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for detecting electrical connection and disconnection on USB type-A charging port","description":"Systems and methods for detecting electrical connection and disconnection on an USB Type-A charging port like power adapters, power banks and car chargers having one or more USB Type-A charging port o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11936231","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
